采用化学气相沉积法在1300℃下制备各向同性热解碳（IPyC），并注入129xe26 +离子，以获得核能领域涂层材料的广泛信息和认识。利用偏振光显微镜、扫描和透射电子显微镜、x射线衍射、拉曼光谱、纳米压痕和x射线光发射光谱等研究了原始和离子注入的IPyC在核石墨衬底上的微观结构。结果表明，Xe离子辐照导致标准多晶样品的物理和化学结构同时发生变化。研究了500℃和1000℃热处理温度对植入IPyC性能的影响。离子辐照导致IPyC沿轴和轴的结构退化，并伴有大面积的碎屑形态出现。有一个剂量窗可以用来调节IPyC的力学性能：辐照后纳米硬度和杨氏模量增加，但随着达到非晶化而降低。
Isotropic pyrolytic carbon (IPyC) prepared at 1300 °C by chemical vapor deposition was implanted with129Xe26+ions to obtain a wide range of information and understanding about the coating materials in nuclear energy field. Microstructure of the pristine and ion-implanted IPyC on nuclear graphite substrate was firstly investigated using polarized light microscopy, scanning and transmission electron microscopy, X-ray diffraction, Raman spectroscopy, nanoindentation, and X-ray photoemission spectroscopy. It was demonstrated that the Xe ion irradiation resulted in concurrent changes in both physical and chemical structures of our standard polycrystalline sample. Influences of the thermal annealing temperature on the properties of the implanted IPyC at 500 and 1000 °C were also studied. Ion-irradiation gave rise to the formation of structural deterioration alongaandcaxis, accompanying with the appearance of widespread clastic morphology among the irradiated zone of IPyC. There was a dose window that could be used to tune the mechanical properties of IPyC: the nanohardness and Young’s modulus increased after an irradiation, but decreased as the amorphization was reached.
